Kingston announces UHS-I U3 SD card range for 4K video

Memory specialist Kingston has announced its fastest ever Secure Digital memory card, the SDHC/SDXC UHS-I U3 (Kingston part #: SDA3/xxGB). This card will be made available in capacities of 16GB, 32GB and 64GB and offers speeds of 90MB/s read and 80MB/s write which is up to nine times faster than standard Class 10 SD cards. Kingston says this new memory card range is especially useful for both professionals and consumers to record 4K and other HD video resolutions.

Kingston's SDA3/xxGB range exceed the SD Association's latest specification, UHS-I U3 (Ultra High-Speed Bus, Speed Class 3), which guarantees performance of at least 30MB/s read and write. That minimum is set as recommended for the record and playback of 4K video without any stutters or interruption. The 90MB/s read and 80MB/s write speeds are said to "ensure the best video and photo integrity by reducing stutter as well as faster PC upload time".
